Patented Feb. 7, 1933 ZAN RUCHIN, F BAY SHORE, NEW YORK REVOLVING WINDOW SASBI Application filed March 20, 1931; Serial No. 524,113.

' My invention relates to windows and refers particularly to revoluble window sashes.

Among the objects of my invention are window sashes capable of revolution within the window frames to allow of the cleansing of the outside surfaces of the window glass carried thereby, means whereby any desired degree of revolution can be obtained, means whereby the sashes will be automatically locked in normal position when revolved thereto, means whereby the sashes will be maintained in any revolved position, means whereby the access of air will be completely prevented when the sashes are in normal position with or without the use of weather strips and a construction of mechanism which is of low cost, easy of operation and which can be readily applied to windows of different sizes without the employment of expert labor.

The usefulness of windows of such construction as to allow of access to the outside faces thereof is universally appreciated and attempts have been made to produce devices of this character butnone of these has possessed the above mentioned necessary and valuable attributes.

The device of my invention, therefore is of new and novel construction and possesses many useful properties not previously known in devices of this character. Y

In the accompanying drawings illustrating one form of the device of my invention similar parts are designated by similar num-erals.

Figure 1 is a front view of a window frame carrying sashes of my invention.

Figure 2 is an enlarged section through the line 2-2 of Figurel, showing the re'- volved sashes in dotted lines,

Figure 3 is-an enlarged section through theA line 3 3 of Figure 1.

Figure 4 is an enlarged section through the line 4-4 of Figure 1.

Figure 5 is a view of the lower right hand portion of Figure 4 showing the sash unfastened from the windowframe preliminary to its revolution.

Figure 6 is a vertical `elevation showing a sash in revolved its guide.

Figure 7 is a section through the line 7-7 of Figure 4. l The particular form of my invention shown 1n the accompanying drawings comprises a wlndow frame having the top 10, the bottom 11 and the sides l2 and 13. The inner face of each side ,12 and 13 carries an extended vertical guide 14, 15 and 16. The frame 6 bottom llfcarries the horizontal base member 17 extending outwardly of a room, the false bottom 18 and the ledge member 19 extending inwardly of the room. The false bottom 18 carries the metallic weather strip 20. The 65 lower portion of each inner face .of the frame position with respect to Vsides 12 and 13 between the members 15 and 16 carries a metallic weather strip 21 and the upper portion of each inner face of the frame sides 12 and 13 between the members 14 and 70 15 carries a metallic weather strip 22.

Each window sash consists of the top 23, the bottom 24 and the two sides 25 and 26.

A window sash guide consists of a double U-shaped metallic member having the base 27, the two outwardly extended members 28, 28, which are extended into the members 29, 29, parallel to the base 27, thence into the two inwardly extended members 30, 30, parallel to the members 28, 28, and thence into the two members 31, 31, parallel to the base 27. Pivot-ally attached by the pivot 32 to the base 27 of the described portion of the window sash guide is the base 33 of a metallic member which base 33 is extended into the 85 members 34, 34, thence into the members 35, 35, parallel to Vthe base 33. Two flat springs 36, 36, abut upon the face of base 33, at 37 and are movable thereon are attached at 38 to the base 27 tending to force these two base 90 members apart, the springs being forced through Openings 39, 39, in the base 27 when the base members 33 and 27 are moved toward each other. The pivot 32 passes through an opening in the base 4() of an an- 95 gular metallic member and into the side of the window sash. The last mentioned angular metallic'member is ii'xedly attached to a side of the window sash' by means of the nails 41,

41.` A flat spring operating member 42 ex- 100 y tended downwardly between the base members. 40 and 33 and has an extended portion 43 capable of placement upon the upper face of the top of a window sash.

Each side of the window sashes carries one of the above described window sash guides.

Attached to each side of each window sash at 44 is a sash cord 45 passing over a pulley 46 and carrying a sash weight (not shown) within a side of the window frame.

The top 23 of the upper sash has a recess to receive thev weather strip 47 of the top 10 of the frame and the upper sash also carries the weather strip 48. The bottom 24 of the lower sash has a recess to receive the weather strip20. y y

A U-shaped brad 49 passes through holes in the base 34, the operating member 42 and the base 40 into the side of the window sash, thus acting as a pivotal member for the movement of the operating member 42.

The operation of the device is as follows When the device is in its normal position,

' as shown articularly in Figures 1, 2, 3, 4 and 7, the sas es can be moved up and down in the ordinary way, the sashes and their attached guides moving as a unit within the window frame.

When it is desired to ivotally move a window sash, the two members 43( are moved inwardly thus pivotally moving the members 42 causing them to press outwardly against the base members 33 forcing those elements outwardly into the position shown in Figure 5. It will thus be seen that the window sash is now free from contact with the window frame and that the sash can be revolved upon a pivot 32 into the position shown in dotted lines in Figure 2, the revolution being capable of continuance until the entire sash has been reversed thus giving access tothe outer face of the glass carried by the sash,

When it is desired to place a sash in its normal osition, it is revolved into an upright cond1tion when it is automatically fastened in that position by the springs 39, 39, forcing the base member 33 and its elements into the recess of the member 40 iXedly attached to the window sash.

In revolving the lower sash it must be raised sufficiently to clear the weather strip 20, and in revolving the upper sash it should be lowered suiiiciently to clear that ortion of the frame into which it is tted in c osed position. f

My device can be employed without the use of weather strips, but Iillustrate it therewith in order to show its adaptability where weather strips are desired. l

A consideration of my device, as shown and explained indicates that it can be employedrwith ordinary standard windows, as well as those of non-standard size, without changing the window frame and with such slight changes in the window sash that they can be readily and easily performed without expert experience, properties which give them great value.

It will be further noted that either, or both, of the sashes can be employed to admit a desired quantity of air and it is to be particular'- l noted that the constant spring pressure of t e base 33 against the window sash maintains the sash in any degree of revolution, an

- attribute of value and one which is peculiar to my device.

It is to be noted, particularly in Figure 4, that when the sashes of my device are in closed position, they are so interlocked with the window frames as to absolutely prevent access of air therethrough, thus possessing valuable advantages over vthose revoluble sashes in which this particular attribute is not present.

I do not limit myself to the particular size, shape, number, arrangement or material of parts as specifically shown and illustrated as these are given simply as a means for clearly explaining the device of my invention.

What I claim is 1. In a revoluble window sash, in combination, a window frame, vertical guides carried by the inner faces of said window frame adapted for the vertical movement of a window sash guide; a window sash having recesses in opposite sides thereof; a vertical double U-shaped window sash guide positioned between said vertical frame guides and vertically movabletherein; a U-shaped member, the base of which is vertically movable over the exposed face of the ydouble U-shaped sash guide, the legs of said U-shaped member abutting upon the faces of the double U-shaped member, said U-shaped member capable of being horizontally moved into and out of said sash recess preventing and allowing a pivotal movement of said sash with respect to said frame; a pivotal member connecting said sash. said U-shaped member and said doube U-shaped member; resilient means normally retaining the base of said U-shaped member within a sash recess preventing a. pivotal movement of said sash and means adapted to remove said U-shaped member from within said sash recess allowing pivotal movement of said sash upon said pivotal member.

2. In a revoluble window sash, in combination, a window frame; vertical guides car. ried bythe inner faces of said window frame adapted for the vertical movement of a window sash guide; a window sash having recesses in opposite sides thereof; a vertical double U-shaped window sash guide positioned between said vertical frame guides and vertically movable therein; a U-shaped member, the base of which is vertically movable over the exposed face of the double U-shaped sash guide, the le s of said U-shaped member abutting upon t e faces of the double U- shaped member, said U-shaped member capable of being horizontally moved into andout of a said sash recess preventing and allowing a ypivotal movement of said sashwith respect tc said frame; a pivotal member connecting said sash, said U-shaped member and'said double U-shaped member; resilient means normally retaining the base of said U-shaped member within a sash recess preventing a pivotal movement of said sash, an eccentrically pivotal member carried by said sash within each of said sash recesses,` the pivotal v movement of whichI will remove said U- shaped member from a sash recess allowing pivotal movement of saidl sash.
